Austin Zoo curator John Gramieri told KVUE he's been stung before, and it felt like someone put a cigarette out on his hand. Symptoms of the venom include burning pain, swelling, nausea, and itching.

According to the KVUE report, zoo officials have not seen an unusual spike in their population, but Central Texans should be aware of the critters. They're often found in trees such as oaks, oleanders, and plum trees.
